I did some homework and it seems out of all the H/F transmissions there are only 2 transmissions that share both Bell housing case # of P16-1 on the transmission and the outter/main case of P16-1 M2B4 and all ATTS SH P6J M2U4/M2X5/M2R4. The earlier viscous LSDs m2b4 are only diffs to use a 14 bolt. Rest and newer LSD OEM H Trans use a 10 bolt. However the SH trans uses a 14 bolt.

We compared diff specs overall...height etc and seem to be real similar
SH trans in clutch housing has the Fins shaved from factory. The Head of the bolts in the SH trans stick a little further out. So I imagine needed slightly more clearance then M2B4 clutch housing.

Reason I am getting into this is I have a M2B4 missing a rear outter/case and am in search of one. P16-1

Full Transmission Bellhousing and Rear Case ID Chart. If you have any of the following Transmissions that I do not have a ID for please check your transmission and post up and will add to the list. There are 2 ID codes:

Bellhousing/Clutch Housing in Orange will be near the clutch fork and will Read P- something
Rear Case/Main Case in Blue will be above the passenger side axle seal inside the webbing and will Read P-something. It will be stamped upside down.

Post Up and I will update the List!
